GRAIN-CONVEYER FOR BINDERS, 84.0.

SPECIFICATION forming part of Letters Patent No. 475,423, dated May 24, 1892.

Application filed March 6, 1891.

To @ZZ whom it may concern:

Be it known that I, GEORGE SCHUBERT, a citizen of the United States, residing at Walnut, in the county of Bosque and State of Texas, have invented certain new and useful Improvements in Grain-Conveyers for Binders, the.; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of grainconveyers for binders and harvesters, dto., in which arms unfold when started from the outer end of its travel on its forward movement and in that position shift the grain in front of it, and thus shift the grain off the inner end of the platform or deliver such grain to suitable compressors, (not shown or described in this specificatiou,) and such arms fold back at the beginning of its rearward movement and pass back underneath the grain on the platform, as more fully described in Letters Patent of the United States granted to myself, No. 446,473,dated February 17, 1891.

The objects of my present invention are, first, to construct the arm or arms so that they will fold back to a narrow space to retreat to the far end of the platform underneath the grain on the platform and be folded so that they can rise at the far end of the platform without any clear space on the platform; second, to provide a track suitable for the operation of such conveyer; third, to provide means by which clearance is obtained on the inner end of the platform for the arms of the conveyer to fold back without extending the platform too far beyond the inner cutting-point of the fingerbar; fourth, to provide means by which the grain is prevented from swaying down in the slot in which the conveyer operates, and fifth to construct all such parts so as to be simple of construction and lowin cost of production.

Referring to the drawings, Figure 1 is a plan view of a harvester provided with myimprovement. Fig. 2 is a side view of the conveyer, partly in section, taken online l 1, Fig. 1. Fig. 3 is a sectional view on line 2 2, Fig. 1, showing the conveyer and other parts beyond the section-line in full lines. Fig. 4 is a partlysectional view on line 3 3, Fig. l, looking to the rear and showing the trap depressed and Serial No. 384,019. (No model.)

the wire elevated. Fig. 5 is the same View as Fig. 4 and by the trap is elevated in position and the wire is folded down, said view being somewhat enlarged. Fig. (5 isa sectional view on line 4 4, Fig. 5, looking as indicated by arrow. Fig. 7 is a sectional view on line 5 5, Fig. 5; and Fig. S is a side view of the conveyer arms and blocks shown in a folded position. The upper and lower plates of the platform are shown in dotted lines.

Similar letters refer to similarparts throughout the several views.

A designates the platform, which is formed of upper and lower floors or plates of sheet iron b and b', braced by and secured to intervening strips d, d', and d2. Two of such strips a and a form walls o o for the slot A. The slot A is made in the upper plate o of the platform A, for the purposes hereinafter described.

B designates the linger-bar provided with the usual guard-fingers B and a shoe B2 at its inner end.

E is a grain-board of ordinary construction.

In the construction of the platform the lower plate b is secured to the lower face of the linger-bar and the upper plate b is secured to the upper face of the finger-bar B, the strip a2 forming the rear sill of the platform.

C designates a shaft extending through the strips a and a and having its rear bearing in the strip a2 and its frontbearing secured to the finger-bar B and provided with a pinion C on its forward-proj ecting end and a sprocketwheel d, located in the slot A', provided with an endless chain d or its equivalent to operate the conveyer, as hereinafter stated. d2 is an idler over which said chain d extends at the grainward end of the platform A. Said idler is secured to shaft d3, which has its bearings in the strips a and a. (Seen in dotted lines in Fig. 1.)

The grain-board E can be secured to the plates b and b by corner-irons F, one of which is seen in Fig. 2, or in any other suitable manner.

e designates a rod or wire extending over above the conveyer, secured to the grainboard E and extending to t-he stubbleward end of theplatforrn, as seen in Fig. 1. Said wire is placed about an inch or more above the platform A at each end and should be lo- IOO passage-way of the conveyer and any-suitable number of such wires may be employed. The lower halves of the bars a and a are cut out at near their grain end for about ten or` twelve inches in length to receive the guides D D. Said guides are hinged with their stubbleward end to the bars a and a', respectively, projecting with their free ends grainward to Within three or four inches of the lower end of theguides m m. 'The free ends g of said guides are cut slanting, as shown in Fig. 2, and passed over into the passageway of the conveyer, as shown in full lines in Fig. l by the springs D D', which are preferably secured to the plate b', as shown in Fig. l, and resting against the stud D2.

g2 designates notches formed in the inwardprojecting edges of the plate h near the grain end of the platform.

g is a trap hinged with its stubbleward end to the stubbleward edge of the notches gaand made of proper length to rest with its free end on the guide D, as seen in Fig. 2, or it can be made longer, so as to lap over the free end of said guide D, as shown in dotted lines 1 1 present instance) and anti-friction rollers ,"2 and js. Said rollers rotate on the shaft .7, which has a rotary movement in the block J. i To said shaft 7'4 are secured the arms J and J 2, formed about as shown in Figs. l, 2, and 1 3, provided with the shoulder j5 and j.

in Fig. 2. The guide on the rear side of the slot A is formed and operated the same as the one described and shown. Said guides D and trap g form a guide to guide the rollers j and 7" to the top of plate b.v j

fm. m designate guides secured 4to the plate b and the grain-board E, as `seen in Fig. 2. Said guides are to start the arms J and J 2 to an elevated position, as hereinafter stated. The plate h projects beyond the strips a and a one or two inches, as seen in Fig. 3. Said projections form the4 track A2 A2 for the conveyer. The trap g is a part of `such projecting track.

7?. designates a trap secured to a shaft h', and is the full width of the overbearing plate b and long enough to admit the roller j to pass down when said trap is depressed. Said trap is located at the grainward end of the platform nearthe point Where the movement of the conveyer is reversed. The shaft 7L finds its bearing in the stripor bar a, and is provided with a crank 71.2, carrying rods hf* and h4. The rod h4 extends through a bracket h, and is provided with a spring h5, said spring bearing against the bracket 71.6 and the crank h2, thus holding the trap h in a closed position. Said spring is light enough to yield to any pressure applied to the trap h. The rod h4 projects through an eye hs of the rod or Wire i and is provided with a collar hl, resting against said Wire, as seen in Figs. et and 5. The wire i is secured to a shaft i', having its bearing in the strip or bar a, and is provided with a crank t2 on its other end, said crank 'i2 having a dog 3 pivoted toits free end. (Seen in Fig. 2 and in dotted lines in Figs. et and 5.) The crank '2 does not project beyond the strip a, and onlyr the lower part of the dog t3 projects beyond said strip a, as seen in Figs. 7 and 6. Itwill be seen that when the trap h is depressed the crank h2 is shifted to the rear, as seen in Fig. 4, thus elevating the wire i2 by the shoulder k7 on the rod h4 being in contact with said wire z', and said Wire t', being secured to the shaft i', will in turnraise the free end of crank t?, and thus raise the dog 3 to a vertical position,as seen in dotted lines in Fig. 4, allowing the lower end of said dog il to rest on the plate b and thus retain the `wire t' in an elevated position, as seen in Fig. 4, until the dog il is tripped by the `conveyer, as hereinafter described.

K designates a spring secured to plate b" one-third of the space from b to the plate b',

as seen in Fig. 3.

J designates the conveyer-block provided with one or more arms J and J2 (two in the Beneathsaid shoulders are pivoted the rods J 3 and J4, which are provided with anti-friction rollers 7' andj, as seen in Figs. l and 2. Said rods J3 and J 4 are prevented from opening any fart-her to the rear than seen in Fig. 2 by the shoulders t7"'5 and j. The length of the rods J3 and J 4 is proportioned so that when foldedthe roller j will rest on the plate b', while the roller j2 rests against the plate b. The chain d can be extended through the blockJ and secured by a pin or bolt. The bearings o o for shaft j* aresecured to the lower side of the block J.

The operation is as follows: The pinion C receives its rotation from gearing of the harvester. By said pinion movementis imparted tothe conveyer by the sprocket-wheel d and chain d. The conveyer is moved forward, as seen in Fig. 2, pushing the grain in front of it until the rollers j and j reach the tlaps h h,when the pressure of the grain will cause the trap to descend or open and admit the said rollers underneath the plate b andin front of the springs K, when the traps Will rise again, as described. At this time the movement of the conveyeris reversed, and as therollers j and j are in front of the springs K K they will at first be detained, and thus IIO the rods J 3 and J4 are folded back against the arms J and J2, respectively, and said arms are then drawn back by reason of the leverage of the rods J3 and J4, projecting below the block J and folded, as seen in Fig. 8, and as the arms are thus folded down the rods J 2 and J4 will come to bear on the springs K K, depressing said springs until the rollers will readily roll over same. The wires i t' are raised by the depressing of the traps h 7L, as heretofore stated. Said wires are to prevent the grain from falling in rear of the conveyer. While the arms of said conveyer are folding, the said Wires are again folded down, (as seen in Fig. 5,) as the conveyer moves to the rear, by the rollersjandj' coming in contact with the lower end of the dogs t2 122, tripping said dogs, when they will assume the position as seen in Figs. 2 and 5, thus allowing the wires t' t' to fold, as seen in Fig. 5, and as the conveyer, folded as seen in Fig. 2, moving underneath the grain on the platform to the grain end of the platform, nears said end the arms J' and J2 will come in contact with the guides In m, by which said arms are raised to an elevated position, and the rollers jj' will press the guides D, as seen in dotted lines, and pass said guides, when the said guides will be moved back again by the spring D'. The traps g are elevated to a level of the plate b by the anti-friction rollers j2 and l72' and is to prevent said rollers from accidentally disengaging from beneat-h said plate b. As soon as the rollers j and j' have passed the free end of the guidesDthe grainvward movement of the con veyer ceases, and as the conveyer is started on its stubbleward movement the traps g will again drop down to form a continuous track, as heretofore stated, for the rollersj and j' to ascend to the top of plate b, and thus complete the elevation of the arms J and J2 as the conveyer is started on its forward movement. The constructions and operations yof the track on the other side of that just described are the same as that just described.

Having thus described my invention, what I claim is j 1. In a grain-conveyer forself-binding harvesters, the combination of a conveyer head or block J, having a shaft j4, provided with anti-friction rollers `7'2 and t72 on its projecting ends, arm or arms J and J2, secured to said shaftj4 and provided With shoulders or projections 3'5 and j, arms or rods J3 and J4, pivoted to said arms J and J2 beneath the shoulders j and js, anti-friction rollers j and j on the lower or free ends of the arms J 2 and J 4, as shown, a plat-form provided with a slot A', having inwardly-projecting edges A2 A2, having traps formed in said inwardly-projecting edges, sprin gs K Kin said platform, and means to operate said conveyer, substantially as shown and described.
